Paul described perfectly a life turning to Jesus. The key is a heart turning more and more to Jesus and more and more away from sin. God will judge if we have done this.
"not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith--that I may know Him and the power of His resurrection, and may share in His sufferings, becoming like him in His death, that by any means possible I may obtain the resurrection from the dead. Not that I have already obtained all this or am already perfect, but I press on to make it my own, because Christ Jesus has made me His own. Brothers I do not consider that I have made it my own. But one thing I do: forgetting what lie behind and straining forward to what lies ahead.I press on toward the goal for the prize of the upward call of God in Christ Jesus." Phiilipians 3:9-14
"In fact, I do not even judge myself...it is the Lord who judges me." 1 Corinthians 4:3-4
It is one thing to deliberately sin and using Grace as a licence to sin, and seeking to sin less and less because of our love realtionship with Christ and His desire for us.
those who say they are saved
are
actually judging themselves
